Question on Rogero 4.41 v1.0 updating to Rogero 4.46

Hello, basically i wanted to update my ps3 cfw i am on Rogero 4.41 v1.0 but is it fine to update over cfw, i haven't done this in a while since new games are coming out and required the 4,46 fw i need to update or is it best to not to because since there's a few stables cfw so what would you all suggest to do? the best alternative ?

also once i update can i revert back to some other cfw like if i am not satisfied can i revert back to Rogero 4.41 or i have to use a flasher to get back to stock and re do the whole process again.

yes you can do that via recovery menu without a flasher (its much dangerous to do things via flasher, even in downgrading process, that's why a good NAND/NOR backup is necessary before doing anything on flash) but I dont see reason why you need to downgrade (except if you want some homebrews that only works on certain firmware version) specially if you use your PS3 mainly for backups
